Comment: Why a 7-day moving average? Wisconsin tends to have cyclical patterns in testing results, with low spots typically on Mondays (this may be due to lower testing on weekends)
### Dane
Active cases: Estimated recovery time from health experts varies between 10-20 days, with a nontrivial proportion of cases being long-term / on-going. Even given the testing lag, a conservative approximation is to use the total number of positive (diagnosed) cases across the last 10 days. We will go with this standard, along with a range from 10-14 days of active accumulation, and adjust as more precise information becomes available. 14 days corresponds with two-week standard in place in MN school decisions.

[1] "The number of cumulative deaths, at a lag of 21 days, are approximately 23.3 times number of cumulative cases to the 0.35 power."
